Background: Cancer is a set of diseases formed by abnormal growth of cells leading to the formation of the tumor. The diagnosis can be made through symptoms’ evaluation or imaging tests, however, the techniques are limited and the tumor detection may be late. Thus, pharmaceutical nanotechnology has emerged to optimize the cancer diagnosis through nanostructured contrast agent’s development. Objective: This review aims to identify commercialized nanomedicines and patents for cancer diagnosis. Methods: The databases used for scientific articles research were Pubmed, Science Direct, Scielo and Lilacs. Research on companies’ websites and articles for the recognition of commercial nanomedicines was performed. The Derwent tool was applied for patent research. Results: This article aimed to research on nanosystems based on nanoparticles, dendrimers, liposomes, composites and quantum dots, associated to imaging techniques. Commercialized products based on metal and composite nanoparticles, associated with magnetic resonance and computed tomography, have been observed. The research conducted through Derwent tool displayed a small number of patents using nanotechnology for cancer diagnosis. Among these patents, the most significant number was related to the use of systems based on metal nanoparticles, composites and quantum dots. Conclusion: Although few systems are found in the market and patented, nanotechnology appears as a promising field for the development of new nanosystems in order to optimize and accelerate the cancer diagnosis.

Abstract THIS ARTICLE REPRESENTS the first of a 2-part exploration of quantum dots (Qdots) and their application to neurological surgery. Spanning from materials science to immunology, this initial review traces the marriage of imaging physics to biochemical specificity. Qdot science now stands poised to dramatically advance the diagnosis and therapy of neurosurgical conditions. Qdot research efforts currently involve several disciplines; this comprehensive review therefore considers multiple fields of inquiry. This first installment discusses 1) Qdot physical properties, 2) established biological and in vivo properties, 3) magnetic resonance imaging applications, and (4) existing cardiovascular and oncologic research. Finally, this review establishes the existing bounds of Qdot possibilities. The second concept article details future endovascular diagnostic and therapeutic methods derived from these seminal advances.
